WINDOW-BUTTON SECURER.

SPECIFICATION forming part of Letters Patent No. 227,978, dated May 25, 1880.

Application iled April 1, 188D.

To all whom t may concern Be it known that I, KATE DUVAL HUGHEs, a citizen of the United States, residing at Washington, District of Columbia, have in- 5 vented a new and useful Security-Clasp for Window-Fastenings, of which the followingis a specification.

My invention is simply a clasp or hook made of spring-Wire placed on a strong screw hav- Io ing a grooved head, as hereinafter explained. A The object of this invention is to secure the window-fastener so effectually that it cannot be opened from the outside. I attain this object by the mechanism illustrated in the accom- I 5 panying drawings, in Whichy Figure l represents the clasp closed and in use. Fig. 2 represents the clasp detached.

In Fig. 2, which represents the security-clasp detached, D represents the screw, and F the zo head of the screw. H is the groovein which the clasp G is placed, and E is the Washer (Model.)

which keeps the clasp firmly in its place, While H is the groove in which the clasp Gr is set and swings round. The head of the screw F and the Washer E form the groove H. 2 5 The groove may be formed by the head of the screw and the Washer, or it may be cut n the steel 5 but the clasp must be set in a groove to render my invention complete.

Having thus described my invention, what I 3o claim, and desire to secure by Letters Patent. 1s

A clasp for securing the fastenings of Win dows, consisting of the wire hook or clasp G, in combination with the screw D, having the 3 5 groove H, substantially as and for the purpose set forth in the above specification.
